Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80678, here are decompositions:
- 7 + 80671 = 80678
- 67 + 80611 = 80678
- 79 + 80599 = 80678
- 151 + 80527 = 80678
- 229 + 80449 = 80678
- 271 + 80407 = 80678
- 331 + 80347 = 80678
- 337 + 80341 = 80678
Showing the first eight; more decompositions exist.
